This blog post comes to you from warm and azure blue waters of Côte d’Azur – That is the French Riviera. All thought that is not important and I really do not consider my self a road warrior, I have been and am traveling more than enough to be extremely annoyed about the conditions and limitations of wifi all over the world. Even here in France, which I consider to be a country of a fairly high living standard, superb cooking and lovely wines and of course Champagne, but still the wifi, internet or 4G always seems to sucks. Of […]

Been using Ubiquiti in the lab for more than a year now. Really like this simplicity of operations, but at the same time I have full access to the linux alike OS underneath. This gives you the possibility to run scripts and other tasks. Which brings me to what this blog post is all about. I have an ISP which charges extra for having a static IP address and me being lazy and cheap (Also it would be more than the monthly cap I have from work), I have not “upgraded” to a static IP. So I thought why not […]

TOC Part 1: The NUC killer: SuperMicro SuperServer E300-8D Part 2: SuperMicro SuperServer E300-8D deep dive Part 2: SuperMicro SuperServer E300-8D deep dive In the last post, I wrote about the SuperMicro SuperServer E300-8D in comparison to Intels NUC series, but also covered networking and the reason for me buying into SuperMicro over NUC. In this next part of the serie. I am going to dig into the E300-8D’s technical specifications, show case its good and bad sides and talk about noise and power consumption. A closer look at E300-8D from the outside Before I dig in deep, let me […]

TOC Part 1: The NUC killer: SuperMicro SuperServer E300-8D Part 2: SuperMicro SuperServer E300-8D deep dive I bought two SuperMicro SuperServer E300-8D a few months ago and they only seems to get better as I get to know them better. The SuperMicro SuperServer E300-8D is replacing my old lab, which was excessively small and inadequate. It was based on Dell PCs, which was limited to only 8GB of memory. With 8GB of memory, there is not much I can get up and running in a state where I was happy with it. Therefore, I was looking for something else. […]

Intel Optane the new benchmark SSD to beat For a very long time Intel 3700 series of SSDs has held the crown as the best all round SSD for the enterprise market. Intel did something special with this line of SSDs. They stop talking IOPS and latency at least as the main focus and started focusing on where it really would hurt mainstream storage vendors. What was new was QoS or consistency and power loss protection. These features are enterprise graded. Many vendors will claim that they have power loss protection, but non-like Intel did and even today, you […]

There I said it, I’m cheap, at least when I can’t go all in. Let’s face it, we can’t all have an enclosure with eight or sixteen blades in it as a home lab, and it would be nice to have at least 32 GB of RAM per host, well it would be down right nice to be able to have 64 or even 128 GB of RAM. But I can’t! Even thought I really would like to, having this kind of equipment at home, is too noise, expensive and would require a lot more maintenance, than I would have time […]

HP Onboard Administrator LDAP Authentication This is a bit out side of what I normally write about, but it still deals with IT and to be honest I used quite some time figuring out how this work, as the documentation is extremely poor in this regard. But once you have figured out, what the developer thought was a smart way to implement this, it is actually quite simple – Not brilliant, but it works and for most cases very well. Getting started with HP OA LDAP Authentication Default HP OA comes with a default Administrator account (yes its case […]

Over the last years I’ve see the same mistake repeated over and over again, to some extend it looks like a complete denial, and even though there have been multiple consultants looking at different performance related issues none of them had questioned whether the servers and their BIOS them self have been setup correctly. More often then not what I’ve seen is that the customer had made no effort to change any BIOS setup, sort of relying on the manufacturer some how knowing what the customer has planned to install on the server. So hopefully the below will help correct […]
